I want to change the return button to say "Search". If I use xtype: 'searchField' in a form, it works however i want to have it in a Panel, as the app is almost done and don't want to go about changing components.

When I was changing my panel to form, I was losing all my UI. After seeing around, found out that if I made the form scrollable false, its UI came back just like the panel. So, that is done.

Also, at one place I am using a Ext.container which happens to be transparent(having UI in the background). If I go about changing this component to form or panel for that matter, how do I make it transparent?
